[PATCH 0/6] A bit better dumb server support

Several days ago there was a discussion on discovering remote tags and branches. This was somewhat related to supporting packed repositories on a dumb server I have been toying with, so here is my current status.

The first three patches deal with the discovery of remote tags and heads:

  [PATCH 1/6] git-peek-remote: show tags and heads from a remote repository.
  [PATCH 2/6] Documentation: git-peek-remote.
  [PATCH 3/6] git-ls-remote: show and optionally store remote refs.

The discovery over http transport against a dumb server needs to have a couple of files to support it, which is prepared with the next two patches.

  [PATCH 4/6] Add update-server-info.
  [PATCH 5/6] Document update-server-info.

The git-update-server-info command introduced by these two patches prepare not just the list of tags and heads, but the list of packs and commit ancestry information. Using that, cloning a packed repository over http transport from a dumb server becomes trivial.

  [PATCH 6/6] Support cloning packed repo from dumb http servers.

The next task would be to add support of the same to git-fetch.
